Is there an alternative to this verbose syntax in RxJava2 for combining streams?
You have to specify BiFunction and the types explicitly:

observable1
  .withLatestFrom(
    observable2,
    BiFunction { t1: Any, t2: Any -> ... }
  )

Ideally this would just be the following, but it can't be matched:

observable1
  .withLatestFrom(observable2) { t1, t2 -> ...}
